Los Angeles : Actress Julia Roberts is said to be in talks to star in "Train Man", a courtroom drama about a New York-based man who has been arrested several times for stealing various forms of mass transit. Roberts would play a lawyer tasked with defending Darius McCollum, the criminal known for impersonating public transit authorities in order to drive away subway trains and Greyhound buses, reports variety.com. McCollum, who is diagnosed with Asperger's syndrome, has been arrested more than 25 times for such crimes. Roberts' character would be his most recent lawyer, and his previous heists will be shown throughout the film via flashbacks. "It is a meaty role for Roberts, along the lines of her Oscar-winning portrait in 2000's 'Erin Brockovich'," said a source. The script is by Simon Stephenson, while director has not been hired yet. Meanwhile, Roberts has two movies in 2016: "Money Monster" directed by Jodie Foster, and "Mother's Day" from Garry Marshall.
